Abstract:
An object of the invention is to provide material for a battery case which is remarkably reduced in internal contact resistance between the battery case and the anode forming mixture, has an excellent alkali corrosion resistance, and can improve the performance of the battery. Another object of the invention is to provide a battery case using the material and a battery manufactured by using the battery case. The surface-treated steel plate has a nickel-tin alloy layer on the surface of a steel substrate which is to be the internal surface of battery case. The nickel-tin alloy layer is formed on the internal surface of the case formed by deep drawing, etc. Moreover, a battery is manufactured by putting manganese dioxide, graphite, and potassium hydroxide in the case as an anode forming mixture and zinc and potassium hydroxide as an active cathode material.
Abstract:
A thin battery is produced on a surface is taught. A first electrode layer and a second electrode layer are provided on the surface. An electrolyte layer is printed on the first electrode layer and the second electrode layer. The electrolyte layer possesses substantial mechanical strength such that further printings on top of the electrolyte layer can be done. A photopolymerizable protection layer is printed on the electrolyte layer and around a perimeter of the electrolyte layer, wherein the photopolymerizable protection layer solidifies on exposure to suitable radiation. The electrolyte layer comprises at least one first functional group and the photopolymerizable protection layer comprise at least one second functional group such that on exposure to the suitable radiation some of the at least one first functional group makes chemical bonds with some of the at least one second functional group.
Abstract:
An alkaline electrochemical cell having an anode including electrochemically active anode material, a cathode including electrochemically active cathode material, a separator between the anode and the cathode, and an electrolyte. The electrolyte includes a hydroxide dissolved in water. The separator in combination with the electrolyte has an initial area-specific resistance between about 100 mOhm-cm 2 and about 220 mOhm-cm 2 .

Abstract:
Provided is a new charge storage device structure, incorporating a double layer supercapacitor (DLS) material, electrochemical supercapacitor (ECS) material and/or battery material. More specifically, the DLS material, ECS material and/or battery material may form multilayer electrode structures. Additionally or alternatively, the DLS material, ECS material and/or battery material may form electrode structures in which the DLS material, ECS material and/or battery material are in contact with both a common current collector and electrolyte. The present invention can be generalized towards other energy storage devices, opening a new avenue for a large spectrum of device applications.
